San Diego County, San Diego Rat Control Situation:
Hi David, Is a UV blacklight still useful, exterior-wise, if it rains after the rodents leave their urine stains? I am in the process of performing exterior maintenance to better exclude my roof rats. 1) I have a 25 year old cedar shake roof in San Diego California with openings under each shake along the rake edge of the roof at the gable ends of my house. There's no drip edge, i.e. under the shakes I have roofing paper (now somewhat curled) that runs more or less up to and rests right atop the fascia board. Because I have skip sheathing, and since the cross section of a shake is a wedge that is up to one inch at the upper, thick end, this appears to create many huge entry points along the rake edges even though the sheathing is rabbeted into the fascia board. As a result, I'm thinking of getting a UV blacklight to use outside the house to sleuth for urine stains along the upper edge of the gable end shakes and fascia boards. My question is, how easily does the winter rain wash away the urine, rendering this a pointless exercise? 2) I noticed a new product called "rat-out gel" and was thinking of applying it along the rake edges mentioned above. Or, maybe I should just buy many rolls of X-Clude and use that instead. Or maybe both. Any comment? Thanks very much for your website, Doug
My response: First off, I do not have experience using UV lights to detect rat urine. But I do suspect that rain will severely limit the effectiveness of this approach. I have never heard of Rat-Out Gel or XClude, but I typically stick to physical barriers rather than repellent type devices. If your roof makes this impossible, you might have a tough time keeping the rats out.

Symptoms Of A Sick Rat
In most cases, a sick rat will not show any obvious symptoms at the early stage of an illness. But if the rat in question is a domesticated rat, you might notice some physical changes in the rat if you are very observant. Here are some of the common symptoms that you might notice in a sick rat:- Restlessness and irregular breathing
- Eye and nasal discharge and continuous sneezing
- Rapid reduction in body weight
- Body exhaustion and excessive sleeping
- Lack of appetite and crouching behavior
If you notice any of these in a rat, it is an indication that the rat is sick and it needs urgent medical attention. After noticing any of these symptoms, the first thing you need to do is to avoid any form of contact with the rat. Rats are carriers of diseases, so it is best to avoid touching it.
Although, not every sickness of a rat is a result of viral, bacterial, or parasitic infection. Their sickness could also be as a result of physical injuries such as a sprained bone, a broken tail or toenails, or a bite wound from another rat or animal.
Just like other animals, rats are also affected by diseases. If you wish to keep the rat alive, the best thing you can do is to seek medical attention. Rats are very sensitive animals and will not do well when administered the wrong medication. Having shared this, you need to avoid the use of medication that is not prescribed by a veterinary doctor.
